Accuracy of Daily Weights and Fluid Balance in Medical Intensive Care Unit Patients With the Intervention of Electronic Medical Records and Electronic Bedside Weight Measurements

The Correspondence between Fluid Balance and Body Weight Change Measurements in Critically Ill Adult Patients

“…Previous studies have also demonstrated poor reliability of fluid balance measures. Moreover, the correlation with body weight changes did not improve when a correction for indiscernible water loss was made [ 8 , 10 , 13 , 14 , 15 , 16 , 17 ]. Some investigations only focused on net changes [ 10 , 15 , 16 , 17 ] which are subjected to error accumulation, the higher the duration of ICU hospitalization [ 16 ].…”

As there is no consensus in the literature regarding indiscernible water losses, data were presented with and without correction.…”

“…Previous studies [ 8 , 10 , 13 , 14 , 15 , 16 , 17 ] have established that charting fluid balance totals, both under- and overestimated body weight changes in unpredictable patterns. However, short stays in an ICU, enrolment of a specific low-risk population, use of multiple types of scales and emphasis on cumulative fluid balance, prevented generalization of data.…”

A retrospective review of fluid balance control in CRRT

“…The introduction of Clinical Information Systems does offer the advantage of computer generated calculations but the possibility for fluid balance errors remain in the verification of data or when manual data entry is required. 30 The likelihood of errors in daily fluid balance totals was further confounded by output that was not recordable. This study made no allowance for insensible water loss (IWL).…”

Reduction of Cardiopulmonary/Renal Complications with Serum BNP-Guided Volume Status Management in Posthepatectomy Patients

“…2 Change in body weight over time, which is one of the most accurate measures of volume status, is often inadequate because of lack of dependable measurements. 3 Although invasive measures of cardiac output and intravascular fluid status can provide more precise data, a monitored intensive care unit is required and not practical for the routine awake floor patient. Therefore, a better measure is needed to help guide fluid therapy in the postoperative setting after liver resection.…”
